together, the upper two are wide apart ; behind the clitelluni the 

 ventral pair are further apart, while the third seta is placed more 

 dorsally so as to reduce the interval between it and the fourth 

 seta. In the last 25 segments the setae are arranged very 

 irregularly and there may be as many as 5 on each side. 



Male pores on papillae on segment 18. 



Oviduct pores on segment 14. 



Spermathecal pores five in number ; at the level of the ventral- 

 most setae between segments 4 and 5, 5 and 6, 6 and 7, 7 and 8, 



8 and 9. 



Nephridiopores at the level of the third setae. 



Alimentary canal. Gizzard in segment 5 ; vascular swellings in 

 segments 10, 11, 12. No true calciferous glands. 



Blood vascular system. Dorsal vessel single ; hearts in 

 segments 6-12. 



Excretory system. Meganephric. 



Reproductive system. Testes in segments 10 and 11, the 

 ciliated rosettes opening in the same segments. 



Spermiducal glands, long, coiled, tubular, extending over 

 segments 18-27. 



Sperm sacs, lobate ; attached to the j^osterior wall of segment 



9 and the anterior of segment 12. 



Ovaries in segment 13, into which the oviducts open. 



Spermathecae, 5 pairs, in segments 5-9, each consisting of a sac 

 and tubular diverticulum three-quarters the length of the sac. 



Habitat. Gullies amongst the ranges near the source of the 

 River Yarra, Victoria. (Collected by Mr. C. Frost.) 



Cpyptodrilus, Fletcher. 



(1). Cryptodpilus shephardi sp. n. (Figs. 28, 29, 30.) 

 Spirit specimens 6;| inches long, \^ inch broad. 



Prostomium scarcely at all dovetailed into the peristomium. 



Clitellum extending over segments 14-16. A deep depression 

 (in spirit specimens) occupying the mid ventral surface of 

 segments 17 and 18. Accessory copulatory structures in the 

 form of small oval patches ventrally on segments 18 and 10; 

 inconspicuous.
